v2.6.17

# Changelog

## Improvements

- **Resilient DB Component Loading**: Isolate each agent/team load so one bad component is skipped instead of dropping all, fix model provider round-trip on deserialization, register `TuningEngines`, and dedupe the catalog by model class. (#8461)
- **Structural Registry Tool Dedup**: Dedupe re-instantiated toolkits by `(type, name, function set)` so they collapse instead of accumulating duplicate registry entries. (#8450)

## Bug Fixes

- **ParallelTools GA API**: Migrate to the parallel-web >= 1.0 GA surface. (#8453)
- **Slack Search Dual-Token Support**: Support a user token (`xoxp-`) for `search_messages`, which bot tokens can't call. (#8411)
- **Slack HITL Required-Approval DB Gate**: Resolve the DB approval record on approve/reject so `required` rows aren't orphaned. (#8386)
